Considerable difficulty is experienced with metal Window frames made ofdeformed metal ,sheets or plates because of the liability of air-to`find ingress from the outside through the frame structure into theroom.

One of the objects of the presentiinvention is to provide an improvedform of structure that more fully seals the jointsiagainst the passageof air, and at the same time produces a stronger structure than hasheretofore been obtained.

Another and important object is to provide means for more effectivelysecuring packing or calking material in place in the joints between theframe structure and the building Wall .in which such structure islocated.

In the accompanying drawings:

Figure "I is a similar viewof a portion of the parting strip;

yThe jamb box proper consists of a sheet or plate of deformed metal,providing a rear Wall 8, an inner side Wall 9 and an outer side Wall 10,.the latter being narrower than the former. The inner Wall 9 terminatesat its free margin in an inturned flange 1l having an outturned terminalportion l2 providing an inwardly opening groove 13. The outer Wall 10has an inturned flange 14 and the juncture of this iiange with the Walll()l is in the .form of an inset bead 15.

Secured to the flange 14 of the wall 10 of the jamb box is a staffbead,y This also comprises a deformed metal strip or plate having a rearWall 16, an outer Wall 17 and a facing Wall 18 that is inturned from theouter Wall 17 and spaced from the Wall 16. It Will be notedr that therear wall 16 is provided in its outer face with a longitudinal groove 19formed by insetting the metal and this groove snugly receives the beadlformed at the juncture of the Wall l0 and flange 14 of the jamb box.The iiange 14 lies against the rear face of the Wall 16 onthe inner sideof Y the tongue and groove interlocking engagement, and the parts arepreferably secured together by electrical spot Welding, as indicated at20. The

the reariwall 9 of the jainb` box, has an inset portion and an outturnedWall 26 that lies against the inner portion of the wall 16 of the staffbead. This portion 26 is provided on its rear face With a longitudinalrib 2'1 that engages in the 'IQ groove 22 ofthe Wall 16, Between thestaff bead Wallr 1S and the coverstrip 23fis located a parting stripcomprising. afacingfvvall 28 `and rear walls 29 joined. to the partingstrip by outset beads 30. The. outer bead'BO cooperates-with '-75 j theinner edge of th'eistaif bead vvall 18v to 'provide a guide slot 31. rSimilarly the inner bead 30 of the parting strip is spaced from theouter TheY parting strip is held in place byiscrews 33 80 passingthrough theffacing Wall 28 and.. having threaded engagement with therear Wall 16 `of, the'staff bead. The side Walls 29 of theparting fstrip preferably terminate in inturnedbearing anges 34 that bear againstthewall v26 and. thus v,S6 serve to secure the cover strip tothe'walli16- and maintain an interlocking engagement of the bead 27 inthe groove 22,` i

'In Figure l there fis shown portions of the sash, the same beingdesignated 35. These 99 fsashes, asv is vvell known,Y have .outstandingpart of the jamb box and when the frame isY placed in position in a Wallstructure, the main body of vthe jamb box is preferably embedded in theWall. This wall may have a concrete body, asindicated at 37 and be facedWith brick or 100 stone, as 38. The structure vof the Wall, however,Yconstitutes no part of the present invention, l Y but is shown in Figure1 for illustrative purposes. 4 The cover strip and parting strip areremovable to permit the introduction and removal of the '165y sashes andalso to give access to the interior of the jamb box, in which the sashWeights are located.

In this structure two outstanding features are to be noted. Theintertting of the WalllO of l0 y the jamb box and the wall 16 of thestaff bead by reason of the tongue and groove connection 15-19 insures aweather-proof joint that more effectively prevents the passage of airinto the jamb box from the exterior of the building and consequently itsescape into the room. More than that, the channel 2l on the outer sideof the groove l5 in the wall 16 creates an enlarged chamber for thereception of calking or packing between the walls 16 of the stair beadand the wall of the building. Therefore when calking or packing, asshown at 39 is forced into the joint between said wall 16 and thebuilding wall 38, it fills the channel 21 and thus is locked in place sothat the danger of itsl dropping out is greatly lessened. Consequently amore effective seal is provided between the interior of the jamb box andthe exterior of the building than has heretofore been available.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art without further description and it will beunderstood that various changes in the size, shape, proportion andininor details of construction may be resorted to with-- out departingfrom the spirit or sacrificing any of the advantages oi the invention.

What I claim, is:

1. In a hollow metallic frame structure, the combination with a tubularjamb box, of a stai bead at the inner side of the saine and having aportion including a back wall projecting outwardly beyond the saine andadapted to lie alongside the structural wall of the building, saidprojecting portion of the back wall having an inset portion forming alongitudinal channel in its rear face to receive and provide aninterlock for callring material placed between the structural wall andthe'projeeting portion of said back wall of the stai bead. n

2. In a hollow metallic frame structure, the

vcombination with a tubular jamb box having an outer side wall, of astaff bead outstanding from the side wall and having a rear wallprovided in its rear face with a groove and a channel outside thegroove, the sidewall of the tubular jamb box having its free edgeengaged in the groove, leaving the channel exposed .for the reception ofcalking material that engages in and is held against displacement by thewalls of said channel.

3; Ina hollow metallic frame structure, the combination with a tubularjamb box having an outer side wall terminating along its free edge in aninturned flange and having a tongue projecting beyond `said flange, vofa staff bead outstanding from the side wall and having a rear wallprovided in its rear face with a longitudinal groove and a longitudinalchannel outside the groove, the said tongue of the side wall of the jambbox being engaged in the groove and said tongue and flange leaving thechannel exposed for the reception of calking material that engages inand is held against displacement by the walls of said channel. 1

4. In a hollow metallic frame structure, a tubular janib box and stairbead of deformed metal, including a rear wall and an inner or front wallprovided with sash guideways, said rear wall having an inset depressionforming on its interior side a reinforcing bead and providing in itsouter side a groove for the reception of the material of the wall inwhich the frame structure is installed.

5. In a hollow metallic frame structure, a tubular jamb box of deformedmetal having a rear wall, and a staff bead of deformed metal mounted onthe outer side of the jamb box and projecting outwardly beyond thesaine, said staff bead also having a rear wall that extends outwardlybeyond the jamb box, said rear walls each having inset depressionforming on its interior side a reiniorcing bead and providing in itsouter side a groove for the reception of the material of the wall inwhich thefranie structure' is installed.

6. In a hollow metallic frame structure, the combination with a tubularjamb box having a rear wall and outstanding side wall, of a tubularsta'bead at one corner of the jamb box, said staff bead having an outerside Wall located outside the plane of the side wall of the jamb box anda rear wall that extends across the space etween the two s' e walls andtransversely across the outer end ci the side wall of the jamb box, saidrear wall of the staff bead having a groove in its outer side and saidouter end of the jamb boxs side wall engaging in said groove.

. 7. In a hollow metallic frame structure, the combination with a jarnbbox having a rear wall, spaced side walls, one of said side walls beingnarrower the other, and a cover Wall extending froin the wider sidewall, of a tubular stan. bead located in advance o1" the narrower sidewall and including an outer side wall located outside the same and arear wall extending across the free end of said narrow side wall andconnected to the cover wall, said rear wall oi the stair" bead having agroove in its rear side and the free edge of the narrower side wall ofthe jamb box being engaged in the groove.
